Referring to the drawings, the drier D, embodying the invention there illustrated, comprises a cabinet 10 having a front wall 11, side Walls 12, 12a (the cabinet preferably having greater width than depth) a back wall 13, a top wall 14, and a bottom wall 15. Said walls are preferably constructed of sheet metal. The back wall 13 comprises spaced sections 13a, 13?) having heat insulating material 16 such as felt stuffed therebetween. Said cabinet 10 may be provided in the front wall 11 with contiguous double walled doors 1?, 17a having similar heat insulating material 18 stuffed between the spaced walls thereof. Said doors 1'7, 17a are provided at their outer sides with flanges 19, 19a respectively. Said doors may be hinged to the front wall 11 as by hinges 20, 200; secured to the opposite end portions of said end wall, and to said flanges 19, 19a respectively. Flanges 21, 210. are provided at the meeting portions of said doors, the flange 21a of door 17 being adapted, when said doors are in closed position, to overlie a member 22 extending from and secured to flange 21 of door 17. The door 17a is provided with a handle 22a rotatably mounted adjacent flange 21a of door 17a. Rods 23a, 231) are connected to a circular flange 2% on said handle 22a, in diametrically opposite directions, and are adapted to engage the edges of the front wall 11 above and below said door 17a for retaining said doors in closed position. The cabinet 10 may be further provided with angular supporting legs 23 at the corners thereof, and legs 24 at the middle of the front and back walls 11, 13 thereof.

The drier D may be provided with a drying rack R, for mounting clothes or the like to be dri d, slidably supported in said cabinet 11, in a manner hereinafter described, a heating unit H in the lower portion of the cabinet for supplying heat for drying the clothes on the rack, and vent means V for removing the moisture laden air from the drying chamber.

The drying rack R is seen to comprise a rectangular back wall 45 secured to a frame member 46 of angular cross-section consisting of side members 47, i'l'a, top member 48 and bottom member 49, and a front frame member 50 comprising a bottom angular member 51, side members 52, 52a, and a top Z-shaped member 53 having a vertical leg 5% connecting said side members 52, 52a. The upper portions of said front and back frames 50, 46 are connected by angular shaped members 55, 55a, and angular members 56, 56a connect the bottom portions of said front and back frames 50, 46. All of the angular shaped members mentioned above may be secured by welding or in any other suitable manner to make an integral, rugged frame. The back wall 45, preferably constructed of galvanized iron may be soldered to the back frame 46. A screen 57 may be suitably secured to the bottom members 56, 49, 56a, 51 for catching any objects that may fall thru the rack R. The latter is provided with means for hanging clothes or other fabrics to be dried, comprising a series of rods or pipes 60 mounted on cross-members 61 at each end of the rack, said cross-members being attached to angle members 47, 52 at one end of the rack and to angle members 47a, 520. at the other end thereof. Fig. 2, for the purpose of illustration, shows three such cross-members 61 at each end to provide means for mounting three rows of rods 60. Each of the cross-members 61 may be detachably held to the respective angle members by engaging the ends of the cross-member in Z-shaped members 63 each having a downward extending leg 63a secured to said angle members by rivets or in any other suitable manner. The cross-members are preferably obliquely mounted, the rear ends thereof being higher than the front ends, and the hanger members 63 being shaped to receive the cross-members at an angle thereby permitting a person using the drier to conveniently reach the rear rods 60 in each row. The rods 60 are detachably mounted on the cross-members 61, each end of said rods being provided with a transverse groove 64 adapted to engage a horizontal edge 65 of a notched portion 66 in said cross-members 61. Thus quick removal of said rods and cross supporting members is possible to facilitate replacement of any part or disassembly for shipment. As seen in Figs. 3 and of the drawing, the drier is provided with three rows of rack bars 61 there being four of said bars in each row. It is to be understood that any suitable number of rows of rack bars or bars in each row may be provided depending upon the size of drier desired. The rows of bars 60 are preferably arranged in staggered relation to each other so that any objects hanging down from bars of an upper row may hang intermediate the bars in the row below,

, thus permitting all of the rows of bars to be used simultaneously without entanglement of the clothes hung thereon. This is illustrated in the drawings wherein each of the bars 60 of any row are shown not in alignment with the corresponding bars of the remaining rows.

A rod 67 may be secured to the lowest pair of cross-members 61 at the front ends thereof by studs 68 passing thru suitable openings in said members 61. A sleeve 69 preferably of heat insulating material, such as wood, is attached to said rod 67, and serves as a handle for moving the rack R into and out of the cabinet 10, the rack being slidably mounted in said cabinet as will hereinafter appear. Said rod 67 may of course also serve as an additional bar in the lowest row for hang ng clothes thereon. It will be noted that the rack R is wider than it is deep, being of such dimensions that it may be entirely contained within the upper portion of cabinet constituting the drying chamber. Thus the rack R may be easily pulled out of the cabinet and a person using the drier may stand directly in front of the drier when hanging the clothes. Since the rack is not very deep relative to its width the strain on the supporting means for the rack, when the latter is drawn out of the cabinet, is greatly reduced, and all of the rack rods may be within easy reach of the user.

The rack R is preferably supported by means entirely within the cabinet at spaced points on said rack. To that end the latter is provided reaa42c with two similar tubular members 70 of rectangular cross-section, each tubular member 70 being attached to a supporting bracket 71 having an inwardly extending socket 72 for receiving the front ends of said tubular member 70, and a leg portion 73 secured to an upstanding leg 74 of the Z-shaped member 53. The rear end portion of each of said tubular members 70 may be suitably connected to the back plate 45 of the rack R. The connection may consist of a bracket 125 secured to the top edge portion of said back plate by rivets 126 passing thru said back plate and the vertical flange of angle member 48. Said bracket is provided with spaced hanger extensions 127, 128 secured to an inverted T-shaped member 129, the vertical extension 136 of said member 129 being received in the end portion of said hollow tubular member 79 thru an opening 131 in the bottom wall thereof. Said extension 130 may be secured to said member 70 by rivets 132 or in any other suitable manner.

The rack R may be mounted for sliding movement in and out thru the front wall of the cabinet 10. To this end the cabinet is provided with a pair of spaced channel members 133a,

1331) for each tubular member 70, said channel members being symmetrically spaced with respect to the tubular member 70 on either side thereof. The flanges 183e, 133d of said members 133a, 133b, respectively, extend inwardly and receive wheels 134a, 141), journaled on shafts 135a, 1351), respectively, extending from and integral with the horizontal portion of member 129. For

securing said channel members 133a, 133 to the cabinet, the front ends thereof may be received It is thus seen that the rack is suspended in the I.

cabinet for easy sliding movement, since the wheels 134a, 13% on each side of the rack may roll in the channels 133a, 1331 and the tubular members 70 may rotate the wheel 139. Each of wheels 133a, 133D and 139 is preferably mounted on roller bearings (not shown), to afford easy sliding movement. The rack R may be provided with additional guiding means comprising vertical rollers attached to the lower edge of the back plate 45 at spaced points in alignment with the tubular members 70, and rotatably mounted on lugs 76 suitably secured to said back wall. Said rollers 75 are adapted to engage the side flanges 77 of channel-shaped members 73 suitably secured at the front ends thereof to the front wall 11 of the cabinet as by receiving an inturned flange 79 of said wall 11 in notches formed in said side flanges 77 of channel members 78. The rear ends of said members 78 may be secured to the back wall 13 of the cabinet 10 c in any suitable manner. The inturned flange 79 it will be noted also provides supporting means for the lower edge of the doors 17, 17a of the cabinet as is clearly shown in Fig. 4 of the drawing. It will be noted that when the rack R is pushed wholly into the cabinet and the doors 17, 17a are in closed position as shown in Fig. 1, the upper edges of said doors snugly fit against the downwardly extending leg 54 of Z-shaped member 53, and under the horizontal portion 54a The bracket 136 may be pro- 1- the box 30 (looking at Fig. 6) to the left end thereof. Said horizontal portion 54a. in this position of the rack R extends thru the front wall 11 of the cabinet. The tubular members 70 of the rack R also extend thru said front wall 11 passing thru rectangular openings 79a therein. Thus said rack may be pulled out of the cabinet when the doors 17, 170. are opened. The doors 17, 17a when closed are adapted to prevent the rack from sliding out of the cabinet. To keep said doors closed, the upper end of rod 23a passes thru suitable registering openings 120 in the upper edge of door 17a, the horizontal portion 54a of Z-shaped member 53, and in an inturned flange 11a of the upper portion of front wall 11. The lower end of rod 231) passes thru suitable registering openings 121 in the lower edge of door 17a and in flange '79.

The heating unit 1-1 for supplying a heated medium, such as heated air for drying the clothes, comprises an elongated box 30 extending substantially across the lower portion of the cabinet 10. Said box 30 is supported on bottom wall of the cabinet by spaced brackets 31 comprising legs 32 resting on said bottom wall. Said members 31 are riveted to cross-nembers 33 on which the box rests. The legs 32 extend upwardly along the side Walls 34, 34a of the box 30, said leg extensions being enclosed by channel-shaped members 35 having flanges 35a secured to said side walls 34, 34a by riveting or in any other suitable manner. The wall 12a of the cabinet may be provided with an opening 36 in the lower portion thereof for giving access to the heating unit, said opening 36 being closed by a screened door 37 hinged to the side wall as at 38. The door may be provided with a handle 39 having a latch 40 for maintaining the door in closed position.

A screen member a may be provided for protecting the heating unit against injury, said screen preferably being supported above box 30 by brackets 81 having downwardly extending portions 82 received within channel members 35 and abutting the upper end portions of the legs 32, as is illustrated in Fig. 3 of the drawings.

In the illustration shown in the drawings, a gas burner is employed for supplying the drying medium tothe drying chamber above it. However, obviously an electric heater or other heating means may be used.

Gas may be supplied to the heating unit H by inlet pipe 85 connected to a suitable gas supply (not shown) and entering the cabinet 11 thru a suitable opening in the side wall 12a thereof. Said pipe 85 is connected to a branch pipe 86 sup plying gas to two extensions 87, 87a entering the box 30 at one end thereof. Each of said extensions is housed within a compartment 88 formed at one end of said box 39 by walls 89, 89a meeting at 90 to form a V-shaped portion cut from said box 30, Said extensions 87, 87a have suitable nozzle openings for the gas and are provided with valves 91, 91a, respectively, for controlling the flame. A pilot 92 may be provided on an extension 93 of branch pipe 86, said pilot being positioned between the walls 89, 89a having suitable openings 94 for permitting the gas to be lighted within the compartments 88 by said pilot 92.

The box 30 may be provided with short vertical bafile plates 95 extending in opposite directions from the apex 90 of walls 89, 89a, and with spaced plates 96 extending obliquely from wall 34, and spaced plates 97 extending from wall 34a. Said plates 96 and 97 are disposed in parallel relation to each other and overlap to cause the heated air to follow a sinuous course from the right end of thereof, thereby to insure proper and thorough heating of the drying chamber.

The venting means V for removing the burnt gases from box 30, and the moisture laden air from the drying chamber, may comprise a vent pipe 190 interposed in side wall 12 of the drier. Said pipe 100 comprises a channel shaped member 191 extending into the drier and terminating in outwardly bent flanges 103. Said channel memher 101 rests on the bottom wall 15 which is ex tended as at 101a to cover the lower end of said member. Covering the inner side of said channel 101 is a plate 105 having side edge portions 195a bent backwardly and secured to flanges 193 and adjacent portions of wall 12. Said plate 105 is formed with a plurality of spaced openings 106 adjacent the side edges thereof for a purpose hereinafter appearing.

The vent pipe 100 terminates somewhat below the top wall 14 of the cabinet and attached to the upper, open end of said pipe is a Venturi pipe 10? extending thru an opening 14a in said top wall. Attached to said pipe 107 at the upper end thereof is a back draft preventer 108 described in detail in my co-pending application No. 253,014 filed Feb. 9, 1928.

Interconnecting box 30 of heater H and said vent pipe 100 is a short pipe 192. Disposed within said vent 100 is a partition 109 comprising a channel shaped member 109a. Said member 1090. is provided with a bottom 10% and is adapted to guide burnt gases coming from the heater upwardly toward the upper open end thereof.

The flow of burnt gases upwardly thru pipe 190 11 tends to draw air from the drying chamber thru openings 106 into said vent pipe. The mixture of air and burnt gases in vent pipe 106 passes upwardly thru Venturi pipe 107 and out thru the back draft preventer 108.

Received in openings 111, 112 in the bottom wall 15 and top wall 14, respectively, of the cabinet 10 are baflie members 113 supported by brackets 11 1. Said openings 111, 112 are substantially in alignment and provide means for passage of air into, thru and out of cabinet 10 to facilitate evaporation of moisture from clothes or the like articles on the rack R, and to carry said evaporated moisture out of the cabinet, said openings serving as means auxiliary to the venting means V for removing said moisture.

it will be noted that when the doors are open and rack R is fully drawn from the cabinet for either removing objects from the bars 60 or for placing objects thereon, the back wall 15 of the rack entirely closes the opening in the front wall 11 thru which the rack is drawn. Thus, the person using the drier, standing in front of the rack is entirely protected from the heat rising up from the heating unit H which need not be shut off when clothes are being hung or removed,

thus greatly adding to the comfort of the user and to the usefulness of the device. It will be further noted that the person using the drier may quickly and easily pull out the rack and reach any of the bars 60 from directly in front of the rack, and further that notwithstanding the fact that the rack need be pulled out only a short distance, a large number of long bars and large drying space is provided, since the dryer is of g ing, a door for said opening, a rack within said cabinet comprising a prismatic frame open at the front, a plurality of pairs of aligned oblique rack bars removably mounted on said rack frame,

each bar contacting a front and rear side portion of the frame, a row of rods parallel to the front wall of the cabinet mounted at the ends thereof on each pair of aligned rack bars, means for slidably mounting said rack within said cabinet to permit the same to be extended through said opening in said front wall, said means comprising a pair of members fixed to the front and rear top portions of the frame and disposed perpendicular to the front wall of the cabinet, and means within said cabinet for suspendingly engaging said last named pair of members, said rack having a rear wall adapted to close said openings in said front wall of said cabinet upon moving said rack to extended position.

2. A drier comprising in combination, a cabinet having a front wall provided with an opening, a door for said opening, a rack Within said cabinet comprising a prismatic frame open at the front, a plurality of pairs of aligned oblique rack bars removably mounted on said rack frame, each bar contacting a front and rear side portion of the frame, a row of rods parallel to the front Wall of the cabinet, mounted at the ends thereof on each pair of aligned rack bars, means for slidably mounting said rack within said cabinet to permit the same to be extended through said opening in said front wall, said means comprising a pair of members fixed to the front and rear top portions of the frame and disposed perpendicular to the front wall of the cabinet, and eans within said cabinet for suspendingly engaging said last named pair of members, said rack having a rear wall adapted to close said openings in said front wall of said cabinet upon moving said rack to extended position, the rods of one row being in non-alignment with the rods of another row.
